Water balance with hydrated minerals

[matthewsilver]

Dear Jirka, admins and HP1 users,

I am modeling a system with an atmospheric boundary and water flow into a layer of Na2SO4, which can be hydrated to Na2SO4*10H2O (this process and the reverse are simulated with the PhreeqC database I am using). Does HP1 account for the water consumed (by mineral hydration) or released (by mineral dehydration) in the physical flow system (i.e. is the quantity of water in the physical model coupled with the geochemical calculations in PhreeqC)? From what I can tell, the answer is no. If this is correct, any suggestions for how the water balance from mineral hydration and dehydration could be coupled with Hydrus?

Best regards,
Matthew

Dear,

you are correct, water consumed by mineralogical reactions are not accounted for in the distributed version of HPx. However, everything is implemented in a beta version, but it needs to be benchmarked. I will inform you when this is done,

Dear Diederik,

Glad to hear a version accounting for water in mineralogical reactions is in development. I would indeed appreciate hearing when it is released.

Best regards,
Matthew
